Lean Principles

Lean Principles

Five Lean Principles have been described in the book 'Lean Thinking'

1. Specify Value (For which the customer is willing to pay)

• The critical starting point is value as defined by the ultimate customer

2. Identify the Value Stream (all the actions or processes needed to bring a product or deliver value to the customer)

• Idea transformation: concept to market launch

• Information transformation: order-take through scheduling to delivery

• Physical transformation: raw materials to final customer

3. Make the work flow (processes should be made without delay or interruption)

• Every time the flow of work stops it consume resources but generates no value

4. Pull (when the customer wants to receive, not when the supplier wants to provide)

• Overproduction is the worst form of waste as it generate all other waste

5. Pursue Perfection (no end to the process of reducing time, space, cost and mistakes)

• The real benchmark is zero waste, not what your competitors are doing!
